Description

  The present invention relates to a warning device, and more particularly to a warning device that calls attention based on a monitoring result of a region.

In recent years, as a crime countermeasure against children (including the elderly), the location of the child is detected from the location information of the child obtained by, for example, GPS (Global Positioning System), and whether the location is safe is confirmed. It is hoped that.
Under such circumstances, the conventional emergency call system registers the action range of the child in advance. Then, the emergency call system acquires the position information of the mobile phone obtained by the GPS function of the mobile phone. Next, the emergency call system determines whether the position, that is, the location of the child using the mobile phone is within the action range. As a result, the emergency call system notifies the call center or the like only when it is determined that it is out of the action range (for example, Patent Document 1).

Japanese Patent Laid-Open No. 2002-99971 (see paragraphs 0016-0020, FIGS. 1 and 2)

However, in the emergency call system described in Patent Document 1, when registering a child's action range, it is difficult to register through the user's input operation at the site corresponding to the action range. For this reason, the registered area of action or the like may not match the local situation and may be contrary to the intention of the user.
The present invention has been made under such circumstances, and an object thereof is to provide an apparatus capable of registering a user-desired area that matches the local situation.

  In order to solve the above problems, the present invention provides a position information acquisition unit that acquires position information of the device itself, an area storage unit that stores a preset area, the acquired position information, and the area storage. The area of the part is compared, and based on the result of the comparison, the attention part that performs the attention process, the direction information acquisition part that acquires the direction information of the device itself, and either the prohibited area or the allowable area Based on the acquired position information and the orientation information, a boundary determination unit that determines a boundary of the region specified in the input unit, and the boundary determination unit A region determining unit that determines the region designated in the input unit based on a boundary and registers the determined region in the region storage unit.

  According to the present invention, by determining the boundary of the region based on the position information and the azimuth information, the region having the boundary based on the positional information and the azimuth information acquired after confirming the local situation is determined. Can do. Therefore, it is possible to register a user-desired area that matches the local situation.

(Embodiment 1)
FIG. 1 is a block diagram illustrating a configuration example of the alerting device according to Embodiment 1 of the present invention.
1 includes a position information acquisition unit 101, an orientation information acquisition unit 102, an input unit 103, a boundary determination unit 104, a region determination unit 105, and a region storage unit 106. Furthermore, the alert device 100 includes an alert determination unit 107, an alert information acquisition unit 108, an alert information storage unit 109, an alerting unit 110, a display (display unit) 111, and a speaker (sound output unit) 112. As the alerting device 100, a mobile terminal (computer device) such as a mobile phone or a game machine is used.

The position information acquisition unit 101 acquires position information indicating the position of the alerting device 100 (self device). This acquisition is realized by, for example, a GPS function.
The azimuth information acquisition unit 102 acquires azimuth information indicating the azimuth (for example, east, west, south, north) to which the device is directed. The azimuth information acquisition unit 102 can detect the direction (traveling direction) that the user having the alerting device 100 faces by using, for example, an electronic compass.

The input unit 103 is for inputting information such as the type of prohibited area or allowable area. The prohibited area refers to a place where an action of a user (monitoring target person) such as a child is prohibited. Examples of the prohibited areas include areas corresponding to accident sites and areas where entry is prohibited. On the other hand, the permission area indicates a place where the user's action is permitted. As the permission area, for example, there is an area corresponding to a school district.
Examples of the input unit 103 include an operation button, an input pen, a keyboard, and a mouse.

The boundary determination unit 104 determines the boundary of the region specified by the input unit 103 based on the position information acquired by the position information acquisition unit 101 and the direction information acquired by the direction information acquisition unit 102.
The region determination unit 105 determines the region specified by the input unit 103 based on the boundary determined by the boundary determination unit 104. Details of the functions of the boundary determination unit 104 and the region determination unit 105 will be described later.

  The area storage unit 106 stores the area determined by the area determination unit 105. The area here means the permitted area or the prohibited area, and is associated with position information (for example, xy coordinate data) on the map. Note that a series of operations of the alerting device 100 from the determination of the boundary to the determination of the area is performed based on the operation of the input unit 103 by the guardian of the user (for example, a child). A series of operations of the alerting device 100 after determining the area (determination described later, etc.) is performed when a user (for example, a child) carrying the alerting device 100 is acting (for example, returning home from school). To be done.

The alert determination unit 107 compares the position information acquired by the position information acquisition unit 101 with the area stored in the area storage unit 106. Then, the attention determination unit 107 determines whether it is necessary to call attention.
Specifically, the attention determination unit 107 determines whether or not the position indicated by the position information is in an area other than the allowable area (including the prohibited area). This is because if the position of the position information, that is, the user's whereabouts is an area other than the allowable area, it is necessary to call attention to the user (including a guardian in some cases).

As a result of the determination by the attention determination unit 107, the attention information acquisition unit 108 acquires the attention information from the attention information storage unit 109 when it is determined that attention is required. It is assumed that the alert information includes, for example, a message for calling attention, but the configuration is not limited as long as it is possible to call attention.
The alerting unit 110 outputs the alerting information acquired by the alerting information acquisition unit 108. The output destination is, for example, the display 111, the speaker 112, or the like.

  Note that the area storage unit 106 and the alert information storage unit 109 are configured by a storage device such as a memory or a hard disk device, for example. Moreover, the boundary determination part 104, the area | region determination part 105, the alerting determination part 107, the alerting information acquisition part 108, and the alerting part 110 are comprised by processing apparatuses, such as CPU, for example.

  Here, the external appearance of the alerting device 100 is shown in FIG. The alerting device 100 in FIG. 2 includes a plurality of operation buttons (input unit) 103, a display 111, and a speaker 112.

[Register area]
Next, region registration processing in the alerting device 100 will be described with reference to FIGS. 3 and 4. Here, the description will be made on the assumption that the user (the guardian of the child) registers the allowable (or prohibited) area as the action range of the child using the alerting device 100 while checking the site.
FIG. 3 is a flowchart showing a region registration process in the alerting device 100.
First, by the operation of the input unit 103 by the user, the input unit 103 (attention device 100) instructs an allowable area or a prohibited area (step S101). This instruction is performed, for example, by pressing an operation button.

Subsequently, the position information acquisition unit 101 (attention device 100) acquires the position information of the attention device 100. Then, the boundary determination unit 104 acquires the position information from the position information acquisition unit 101 (step S102).
Next, the orientation information acquisition unit 102 (attention device 100) acquires the orientation information of the attention device 100. Then, the boundary determination unit 104 acquires the direction information from the direction information acquisition unit 102 (step S103).

Next, the boundary determination unit 104 (attention calling device 100) determines the boundary of the area (for example, the prohibited area) designated in Step S101 based on the acquired position information and direction information (Step S104).
For example, when the position information and the direction information acquired by the boundary determination unit 104 are the position information p1 (for example, x = 140, y = 36) and the direction information d1 (for example, northeast) in FIG. The boundary determination unit 104 performs the following process. In addition, the xy plane orthogonal coordinate of Fig.4 (a) converts the longitude-latitude coordinate. For example, x = 140 in the position information p1 corresponds to 140 degrees east longitude, and y = 36 corresponds to 36 degrees north latitude.

  The boundary determination unit 104 first determines the slope of a straight line that intersects the direction of the direction information d1 at a right angle. For example, the azimuth information d1 in FIG. 4A indicates the northeast azimuth, for example, and the inclination of the azimuth is 1 (y = x) in the xy plane orthogonal coordinates. Therefore, the boundary determination unit 104 determines an inclination of −1 when determining the inclination of the straight line.

  Next, the boundary determining unit 140 determines a straight line k1 (y = −x + 176) passing through the position (x = 140, y = 36) of the position information p1 in FIG. To do. This straight line k1 represents the boundary of the area (for example, the prohibited area) designated in step S101. That is, the straight line k1 represents a boundary line that represents a boundary whether or not it is a prohibited region, for example.

Returning to FIG. 3, in step S <b> 105, the region determination unit 105 (attention apparatus 100) determines the region instructed in step S <b> 101 based on the boundary determined in step S <b> 104. Specifically, the region determination unit 105 determines a region on the azimuth direction side indicated in the azimuth information d1 from the determined boundary. An example of the area at this time is shown in FIG.
A region Q1 (for example, a forbidden region) in FIG. 4B is expressed as y> −x + 176 (including −x + 176).

  Then, the area determination unit 105 (attention device 100) registers the determined area in the area storage unit 106 (step S106).

[Output processing of alert information]
Next, the alerting information output process in the alerting device 100 will be described with reference to FIGS. 5 and 6. Here, the description will be made on the assumption that, for example, a child carries the alerting device 100.
FIG. 5 is a flowchart showing an output process of alert information in the alert device 100. Here, a case where the prohibited area Q1 in FIG. 4B is registered in the area storage unit 106 will be described as an example.
First, the position information acquisition unit 101 (attention device 100) acquires the position information of the attention device 100. And the attention determination part 107 (attention apparatus 100) acquires the positional information from the positional information acquisition part 101 (step S201).
Subsequently, the attention determination unit 107 acquires a region, for example, the prohibited region Q1 in FIG. 4B from the region information storage unit 106 (step S202).

Next, the alert determination unit 107 determines the necessity of alerting based on the acquired position information and the acquired prohibited area Q1 (step S203). Specifically, the attention determination unit 107 compares the position information with the prohibited area Q1. Then, the alert determination unit 107 determines whether or not the position indicated by the position information is within the prohibited area Q1 (see FIG. 4B). For example, when the position is within the prohibited area Q1, the attention determination unit 107 determines that there is a need for attention.
As a result of the above determination, for example, when the attention determination unit 107 determines that there is no need for attention (No in step S204), the attention determination unit 107 ends the processing. On the other hand, when the alert determination unit 107 determines that there is a need for alert (Yes in step S204), the process proceeds to step S205.

In step S <b> 205, the attention acquisition unit 108 (attention device 100) reads and acquires pre-registered attention information from the attention information storage unit 109.
Then, the alerting unit 110 (attention alerting device 100) outputs the alerting information (step S206). An example of this output is shown in FIG.
In the output example of FIG. 6, the display 111 displays alert information in a text format “That side is dangerous. Be careful.” Further, the speaker 112 outputs voice alert information “That area is dangerous. Be careful.”.

  In the output example of FIG. 6, the case of text display and voice output has been described, but the present invention is not limited to this. For example, the alerting unit 110 may perform alerting processing by image display, moving image display, vibration processing of the alerting device 100, or a combination thereof.

As described above, the alert device 100 according to the present embodiment includes the position information acquisition unit 101 and the orientation information acquisition unit 102, so that after the local situation is confirmed by the user in the alert device 100. The local position information and direction information can be acquired. For this reason, in the alert device 100, the user-desired region input to the input unit 103 can be registered in the region storage unit 106 based on position information and azimuth information that match the local situation.
Therefore, in the alert device 100, for example, an allowable area that allows the child's action range or a prohibited area that prohibits the child's action range (crime scene, accident scene, etc.) can be accurately registered.

  In addition, although the positional information acquisition part 101 in Embodiment 1 demonstrated the case where positional information was acquired with a GPS function, for example, it is not restricted to this. For example, an IC tag in which position information is recorded is previously attached to a predetermined point (electric pole, station premises, etc.). Then, the position information acquisition unit 101 may read and acquire the position information recorded on the IC tag. In this case, the position information acquisition unit 101 uses an IC tag reader.

(Embodiment 2)
The alerting device according to the second embodiment is characterized in that when registering the prohibited area Q1 (see FIG. 4B), registration is performed in consideration of an area overlapping with the registered area.
FIG. 7 is a block diagram illustrating a configuration example of the alerting device according to Embodiment 2 of the present invention. Note that the same parts (including terms) as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and redundant description is appropriately omitted.
7 is replaced with a provisional region determination unit 104A and a region determination unit in place of the boundary determination unit 104, the region determination unit 105, and the region information storage unit 106 of the warning device 100 according to Embodiment 1 of FIG. 105A and an area storage unit 106A. Furthermore, 100 A of alerting devices differ in the point which has the duplication judgment part 201 and the new area | region determination part 202 from the case of Embodiment 1. FIG. Other configurations of the alerting device are the same as those in the first embodiment.
Hereinafter, a description will be given centering on differences from the first embodiment.

The provisional area determination unit 104 </ b> A determines the boundary of the area specified by the input unit 103 based on the position information acquired by the position information acquisition unit 101 and the direction information acquired by the direction information acquisition unit 102. This determination process is the same as the determination process in the boundary determination unit 104 in FIG.
Then, the provisional area determination unit 104A determines the area designated in the input unit 103 as provisional area information based on the determined boundary. The provisional area is because a part thereof may be removed by the new area determination unit 202 described later. That is, at this point, the area of the area information is not deterministic but provisional. The provisional area determination process is the same as the determination process in the area determination unit 105 in FIG.

The area determination unit 105A determines a new area (referred to as a new area) determined by the new area determination unit 202 described later as an area (for example, a prohibited area) specified in the input unit 103. Then, area determination unit 105A newly registers a new area in area storage unit 106A.
The area storage unit 106A sequentially registers the new areas determined in the area determination unit 105A. That is, new areas are sequentially accumulated in the area storage unit 106A.

The overlap determination unit 201 compares the provisional region determined by the provisional region determination unit 104A with the region registered in the region storage unit 106A, and determines the overlap between both regions.
The new area determination unit 202 determines part or all of the provisional area as a new area based on the result of the overlap determination in the overlap determination unit 201. For example, in the overlap determination unit 201, when the prohibited areas partially overlap each other, the new area determination unit 202 sets the area obtained by removing the overlapping part with the registered area from the temporary area as a new area (prohibited area). To do.

[Register area]
Next, region registration processing in the alerting device 100A will be described with reference to FIGS. Here, the description will be made on the assumption that the user (the guardian of the child) newly registers the allowable (or prohibited) area as the action range of the child using the alerting device 100A while checking the site. .
FIG. 8 is a flowchart showing a region registration process in the alerting device 100A. Of the steps S201 to S210 in FIG. 8, the three steps S202 to S204 are the same as the processes in steps S101 to S103 in FIG. Therefore, the following description will focus on steps other than steps S202 to S204.
In step S <b> 201, the input unit 103 instructs the correction mode by an operation on the input unit 103 by the user. The input unit 103 in the present embodiment includes an operation button for the correction mode, and an instruction to the correction mode is given by pressing this operation button. Then, the process of step S202-S204 is performed similarly to the process of step S101-S103 of FIG. 3, and it progresses to step S205.

In step S <b> 205, the provisional region determination unit 104 </ b> A (attention device 100 </ b> A) is designated by the input unit 103 based on the position information acquired by the position information acquisition unit 101 and the direction information acquired by the direction information acquisition unit 102. The determined area is determined as a provisional area.
Specifically, first, the provisional region determination unit 104A prohibits FIG. 9A based on, for example, the position information p11 (x = 135, y = 36) and the direction information (south) in FIG. An area boundary k11 (y = 36) is determined. Then, the temporary area determination unit 104A determines the prohibited area designated by the input unit 103 as the temporary area Q10 based on the boundary k11 in FIG. The provisional region Q10 at this time is represented by an inequality of y <36 (including 36).

  Next, in step S206, the duplication determination unit 201 (attention device 100A) compares the provisional area determined in step S205 with the area registered in the area storage unit 106A, and determines the duplication of both areas. To do. This determination is made from the inequalities representing the respective areas. In step S207, the new area determination unit 202 determines, as a new area, an area obtained by removing an overlapping part with the registered area from the temporary area based on the determination result in the overlap determination unit 201.

Specifically, in step S206, the duplication determination unit 201 compares, for example, the provisional area Q10 in FIG. 9A and the registered area Q21 in FIG. 9B. The inequality of the provisional region Q10 is represented by y <36 (including 36), and the inequality of the region Q21 is represented by x> 136 (including 136). Therefore, the overlap determination unit 201 determines from the two inequalities that the overlap between both regions Q10 and Q21 occurs in the region where x> 136 and y <36.
Then, in step S207, the new area determination unit 202 (attention device 100A) is registered in FIG. 9B from the temporary area Q10 in FIG. 9A based on the determination result in the duplication determination unit 201. A region (x <136, y <36: including x = 136, y = 36) from which an overlapping portion (x> 136, y <36) with the region Q21 is removed is a new region Q11 in FIG. 9B. Determine as.

Next, the area determination unit 105A (attention device 100A) uses the new area determined in step S207 (for example, the new area Q11 in FIG. 9B) as the area specified by the input unit 103 (for example, the prohibited area). ) (Step S208).
When there is no instruction to change the normal mode in the input unit 103 (No in step S209) and the processing in steps S202 to S208 is performed, a new area that does not overlap with the registered area is further determined. .
On the other hand, when there is an instruction to change the normal mode in the input unit 103 (attention device 100A) (Yes in step S209), the region determination unit 105A registers the new region determined in step S208 in the region storage unit 106A ( Step S210).

Here, the change of the new area when the designation of the prohibited area is performed three times in step S209 in FIG. 8 will be described with reference to FIGS. 10A to 10D.
First, the new area Q12 in FIG. 10A is determined based on the position information p12 and the azimuth information d12 by the processing from steps S201 to S208 in FIG.
Subsequently, the new area Q13 in FIG. 10B is determined based on the position information p13 and the azimuth information d13 by the processing from steps S201 to S208 in FIG.
Next, the new region Q14 in FIG. 10C is determined based on the position information p14 and the azimuth information d14 by the processing from steps S201 to S208 in FIG.
Then, in step S209 in FIG. 8, when the input unit 103 is instructed to change to the normal mode (Yes in S209), the region determining unit 105A determines the region Q15 in FIG. 10D as a new region.

  As described above, the alerting device 100A according to the present embodiment includes the provisional region determination unit 104A that determines the region designated in the input unit 103 as the provisional region based on the position information and the orientation information, And an overlap determination unit 201 that determines overlap between the provisional region and the region of the region storage unit 106. Furthermore, the alerting device 100A specifies a new area determination unit 202 that determines a part or all of the provisional area as a new area based on the determination result of the duplication determination unit 201, and designates the new area in the input unit 103. And an area determination unit 105A for registering the determined new area in the area storage unit 106. For this reason, in the area storage unit 106, areas corresponding to the types of prohibited areas or allowable areas are registered without overlapping.

(Embodiment 3)
The alerting device according to Embodiment 3 is characterized in that, when a designated area is determined, the boundary of the area is corrected based on the map information and the area is determined.
FIG. 11 is a block diagram illustrating a configuration example of the alerting device according to Embodiment 3 of the present invention. Note that the same parts (including terms) as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and redundant description is appropriately omitted.
The alerting device 100B of FIG. 11 has an area determining unit 105B instead of the area determining unit 105 of the alerting device 100 in Embodiment 1 of FIG. Furthermore, the alerting device 100B is different from the first embodiment in that it includes a map information storage unit 301 and a boundary correction unit 302. Other configurations of the alerting device are the same as those in the first embodiment.

Hereinafter, a description will be given centering on differences from the first embodiment.
The map information storage unit 301 stores map information corresponding to position information (x coordinate, y coordinate). The map information represents a map including roads, rivers, and tracks.
The boundary correction unit 302 reads out map information corresponding to the position information on the boundary determined by the boundary determination unit 104 from the map information storage unit 301. Then, the boundary correction unit 302 compares the position of the determined boundary with the position of the boundary on the map represented by the map information.
The boundary correction unit 302 corrects the positional deviation when the positional deviation of the compared position is equal to or less than a preset threshold value. The positional deviation is determined based on the angle between the two boundaries and the distance between the two boundaries, which will be described in detail later.

  The region determination unit 105B determines a region specified in the input unit 103 based on the boundary corrected by the boundary correction unit 302.

[Register area]
Next, region registration processing in the alerting device 100B will be described with reference to FIGS. Here, the description will be made on the assumption that the user (the guardian of the child) newly registers an allowable (or prohibited) region as the child's action range using the alerting device 100B while checking the site. .
FIG. 8 is a flowchart showing a region registration process in the alerting device 100B. Of the steps S301 to S311 in FIG. 11, the five steps S301 to S304 and S311 are the same as the processes in steps S101 to S104 and S106 in FIG. Therefore, the following description will focus on points that are different from the steps in FIG.

In step S <b> 305, the boundary correction unit 302 (attention device 100 </ b> B) acquires map information from the map information storage unit 301. Specifically, when acquiring the map information, the boundary correction unit 302 stores the map information corresponding to the position information (x coordinate, y coordinate) at which the boundary determined by the boundary determination unit 104 is stored in the map information. Read from the unit 301.
Next, the boundary correction unit 302 compares the position of the boundary determined in step S304 with the position of the boundary on the map represented by the acquired map information (step S306), and the positional deviation between both the boundaries is determined. It is determined whether or not it is equal to or less than the threshold value (step S307).

Specifically, in step S306, the boundary correction unit 302, for example, the boundary k31 (x = 135) in FIG. 13 determined in step S304 and the boundary on the map, that is, k41 (y = 4x in FIG. 13). Compare position with -500). At this time, the angle θ formed by the two boundaries k31 and k41 and the distance r between the two boundaries k31 and k41 are compared.
The distance r represents a straight line distance between the position p31 (obtained by the position information obtaining unit 101) and the position p32. The position p32 indicates the intersection of a straight line (west direction) orthogonal to the boundary k31 and passing through the position p31, and the boundary k41.

  Next, in step S307, the boundary correction unit 302 determines whether the positional deviation between both the boundaries k31 and k32 in FIG. 13 is equal to or less than a preset threshold value. The misregistration here is determined from the angle θ and the distance r in FIG. Therefore, there are two types of threshold values, the angle θ and the distance r. These threshold values are stored in the internal memory of the boundary correction unit 302.

Then, when the boundary correction unit 302 determines that the compared positional deviation between the boundaries is not equal to or less than the threshold value (No in step S307), the process proceeds to step S308. In this case, it means that both the angle θ and the distance r are not below the threshold value.
In step S308, similarly to the case of step S105 in FIG. 3, the region determination unit 105B determines the region (eg, the prohibited region) designated in step S301 based on the boundary determined in step S304.

On the other hand, if the boundary correction unit 302 determines that the above-described positional deviation between the boundaries is equal to or less than the threshold value (Yes in step S307), the process proceeds to step S309.
In step S309, the region correction unit 302 corrects the boundary position shift determined in step S304. Specifically, the area correction unit 302 corrects the boundary determined in step S304 so that the positional deviation from the boundary on the map becomes small. For example, in step S307, the region correction unit 302 sets the displacement value (angle θ, distance r in FIG. 13) having a large threshold value to 0. Alternatively, the region correction unit 302 may set the position deviation value to be equal to or less than the threshold value.

  Next, the area determination unit 105B (attention device 100B) determines an area (for example, a prohibited area) instructed in step S301 based on the boundary corrected in step S309 (step S310). This determination process is the same as step S105 in FIG. 3 except that the corrected boundary is used.

  Then, the area determination unit 105B (attention device 100B) registers the determined area in the area storage unit 106, similarly to step S105 in FIG. 3 (step S311). In this way, the area storage unit 106 registers an area having a boundary close to the position of the boundary on the map.

(Embodiment 4)
The alerting device in the fourth embodiment is characterized in that the function of the alerting device in the first embodiment is distributed to two devices.
FIG. 14 is a block diagram illustrating a configuration example of the area registration device 400 and the alerting device 500 according to Embodiment 4 of the present invention. Note that the same parts (including terms) as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and redundant description is appropriately omitted. Note that the area registration device 400 and the alerting device 500 are mobile terminals such as mobile phones and game machines, respectively.
The area registration device 400 in FIG. 14 is different from the alerting device 100 in the first embodiment in FIG. 1 in that it further includes a second input unit 401 and a transmission unit 402.
As the first input unit 103, for example, an operation button, an input pen, a keyboard, a mouse, or the like is used for the second input unit 401.
In response to a request from the second input unit 401, the transmission unit 402 reads the region from the region storage unit 106 and transmits it to the alerting device 500. An example of a request method from the second input unit 401 is a method of selecting a desired region through a user interface on which a plurality of regions are displayed.

14 further includes a reception unit 501 that receives an area transmitted from the transmission unit 402 of the area registration device 400. And the area | region memory | storage part 106 of the alerting device 500 differs in the point which stores the area | region received by the receiving part 501 from the case of Embodiment 1 of FIG. Other configurations of the alerting device and the registration area device are the same as those in the first embodiment.
As described above, even if the area registration device 400 and the alerting device 500 of the fourth embodiment are configured, the effects of the first embodiment can be obtained.

  In the fourth embodiment, the case where two devices are used has been described. However, the functions may be distributed to three or more devices.

  The alerting device of the present invention is useful for registering an area representing the action range of a child or the like and its type (prohibited, allowed) while confirming the local situation. In particular, since the above-mentioned area can be registered while actually confirming the situation of roads, railways, rivers, etc., a mobile terminal such as a mobile phone is suitable as a warning device.
